@illiteratewriter :

Is this issue also present when reading this.context here?

@aaronmars I didn't get the question

[aaronmars]

Sorry, I meant to link to Dropdown.js, line 341:
https://github.com/reactstrap/reactstrap/blob/master/src/Dropdown.js#L341

Just wondering if the context vs. props issue is present there as well.

[illiteratewriter]

That context is just to figure out if the Dropdown is wrapped inside an InputGroup. That one will be empty unless you wrap an InputGroup around the Dropdown. That works as expected.

Thanks for the clarification!
